1. A flow cytometer flow cell, comprising:

  • a transparent flow cell having a hollow flow capillary to allow the flow of a sheath liquid therethrough, wherein said transparent flow cell comprises a solid-state material having an index of refraction that is greater than that of said sheath liquid, wherein particles suspended in said sheath liquid will produce scattered light from a laser beam directed at said particles, wherein a first portion of said scattered light will propagate into said solid-state material of said transparent flow cell; and

    a detector positioned to detect a second portion of said first portion of said scattered light.
